Struct winit::platform_impl::linux::x11::util::cookie::GenericEventCookie

source ·

pub struct GenericEventCookie {
    cookie: XGenericEventCookie,
    xconn: Arc<XConnection>,
}

Expand description

XEvents of type GenericEvent store their actual data in an XGenericEventCookie data structure. This is a wrapper to extract the cookie from a GenericEvent XEvent and release the cookie data once it has been processed

Implementations§

source §

impl GenericEventCookie

source

pub fn from_event( xconn: Arc<XConnection>, event: XEvent, ) -> Option<GenericEventCookie>

source

pub fn extension(&self) -> u8
